Fuzzy logic two-phase traffic signal control for coordinated one-way streets

Abstract

The specific goal of this study was to compare the differences in various traffic signal control algorithms when simulating two consequent one-way intersections with no turning traffic. The opportunities offered by fuzzy logic for controlling traffic are the subject of our FUSICO (FUzzy logic SIgnal group COntrol) research project. The compared algorithms used in the simulations were coordinated fixed-time signal group control, traffic-actuated gap-seeking non-coordinated signal group control, traffic-actuated FUSICO, and a combination of standard traffic-actuated control and a FUSICO controller. This study was our first attempt to use fuzzy methods in coordinated traffic signals; the results were promising. All previous results of the FUSICO project have indicated better overall efficiency than traditional vehicle-actuated control.
